We have just the thing for your friend, but it’s still a few months away. What we can do is include the DIY kit components inside of the Lantern enclosure, but not include the solar or battery. Would that be useful?
Since the PATCH has an SMA connector at the end of its short wire, maybe Outernet could sell adapters on their website. I know you can find them on Amazon, but it becomes a bit complex as there are RP-SMA adapter in use too. Depending what kind of connection you are trying to make, you may need both Standard and RP-SMA.
